There was a complaint that the naming is inaccurate. That's probably
right. Just use the official name instead, which is a bit clunky, but
surely correct.
This was in sub/, because the code used to be specific to subtitles. It
was extended to automatically load external audio files too, and moving
the file and renaming it was long overdue.
The value 0 was treated specially, and effectively forced the increment
to 1. Interestingly, passing 0 or no value also does not include the
scale (from touchpads etc.), but this is probably an accidental behavior
that was never intentionally added.
Simplify it and make the default increment 1. 0 now means what it
should: the value will not be changed. This is not particularly useful,
but on the other hand there is no need for surprising and unintuitive
semantics.
OARG_CYCLEDIR() failed to apply the default value, because
m_option_type_cycle_dir was missing a copy handler - add this too.
This was completely broken. It was checked manually in some config
loading paths, so it appeared to work. But the intention was always to
completely disable reading from the normal config dir. This logic was
broken in commit 2263f37d.
The manual checks are actually redundant, and are not needed if
--no-config is implemented properly - remove them.
Additionally, the change to load the libmpv defaults from an embedded
profile also failed to set "config=no". The option is marked as not
being settable by a config file, and the libmpv default profile is
parsed as a config file, so this option was rejected. Fix it by removing
the CONF_NOCFG flag. (Alternatively, m_config_set_profile() could be
changed not to set the "config file" flag by default, but I'm not
bothering with this.)
This puts in place the machinery to merely append dropped file to the playlist
instead of replacing the existing playlist. In this commit, all front-ends
set this to false preserving the existing behaviour.
Removes some more internal API calls from the Lua scripting backend.
Which is good, because ideally the scripting backend would use libmpv
functions only.
One awkwardness is that mouse sections are still not supported by the
public commands (and probably will never), so flags like allow-hide-
cursor make no sense to an outside user.
Also, the way flags are passed to the Lua function changes. But that's
ok, because they're only undocumented internal functions, and not
supposed to be used by script users. osc.lua only does due to historical
reasons.
This was requested. It was more or less present internally already and
used for Lua scripting. Lua will switch to the "public" functions in
the following commits.
Nobody wanted to restore this, so it gets the boot.
If anyone still wants to volunteer to restore menu support, this would
be welcome. (I might even try it myself if I feel masochistic and like
wasting a lot of time for nothing.) But if it does get restored, it
should be done differently. There were many stupid things about how it
was done. For example, it somehow tried to pull mp_nav_events through
all the layers (including needing to "buffer" them in the demuxer),
which was needlessly complicated. It could be done simpler.
This code was already inactive, so this commit actually changes nothing.
Also keep in mind that normal DVD/BD playback still works.
If the request contains a "request_id", copy it back into the
response. There is no interpretation of the request_id value by mpv; the
only purpose is to make it easier on the requester by providing an
ability to match up responses with requests.
Because the IPC mechanism sends events continously, it's possible for
the response to a request to arrive several events after the request was
made. This can make it very difficult on the requester to determine
which response goes to which request.
So successful playback and user quit can be distinguished, for whatever
reason you may want to do this.
Normally, the "quit" command can be customized, but this does not work
for quit commands sent by the terminal signal handler. One solution
would be introducing something like "ON_SIGNAL" (equivalent to
"CLOSE_WIN"), but considering there are a bunch of possible signals, I'd
rather not get into this. So go with the dumb solution.
Probably fixes#2029.
This command has been deprecated in the 0.8.x and 0.9.x releases - get
rid of it. Its only point ever was MPlayer compatibility, which broke
years ago anyway.
Wnile it seems quite logical to me that commands use _ as word
separator, while properties use -, I can't really explain the
difference, and it tends to confuse users as well. So always
prefer - as separator for everything.
Using _ still works, and will probably forever. Not doing so would
probably create too much chaos and confusion.
Only absolute percentage seeking was permitted first. It is now also
possible to seek by relative percentage.
MPSEEK_FACTOR is used as seek_type.
Fixes#1950.

Until now, we just blocked SIGPIPE globally. Fix it properly to get away
from it.
MSG_NOSIGNAL should be widely available and is part of the POSIX.1-2008
standard. But it's not available on OSX, because Apple is both evil and
retarded. Thus we continue to ignore the problem on such shitty systems.
They are not really interesting. At least one user complained about the
noise resulting from use with shell scripts, which connect and
disconnect immediately.
Now the rescan_external_files command will by default reselect the audio
and subtitle streams. This should be more intuitive.
Client API users and Lua scripts might break, but can be fixed in a
backward-compatible way by setting the mode explicitly.
Why did this exist in the first place? Other than being completely
useless, this even caused some regressions in the past. For example,
there was the case of a laptop exposing its accelerometer as joystick
device, which led to extremely fun things due to the default mappings of
axis movement being mapped to seeking.
I suppose those who really want to use their joystick to control a media
player (???) can configure it as mouse device or so.
This gets rid of the need for a second (or more) parameters; instead it
can be all in one parameter. The (now) redundant parameter is still
parsed for compatibility, though.
The way the flags make each other conflict is a bit tricky: they have
overlapping bits, and the option parser disallows setting already set
bits.
MPlayer requires numeric values for input command parameters. mplayer2
also did. mpv changed these to choices using symbolic strings a long
time ago, but left numeric choices for compatibility.
Add MP_KEY_MOUSE_ENTER to the ignored input if the user has disabled
mouse input. Remove one instance of code duplication, and add a
MP_KEY_IS_MOUSE_MOVE macro to summarize events that are caused by moving
the mouse.
Makes all keys documented in XF86keysym.h mappable. This requires the
user to deal with numeric keycodes; no names are queried or exported.
This is an easy way to avoid adding all the hundreds of XF86 keys to
our X11 lookup table and mpv's keycode/name list.
Happens to fix#1581 due to an unfortunate interaction with the way the
VO does not react to commands for a while if a video frame is queued.
Slightly improves other situations as well, if the client spams mpv with
commands during playback.
These commands are counterparts of sub_add/sub_remove/sub_reload which
work for external audio file.

(minor simplification)
New command `mouse <x> <y> [<button> [single|double]]` is introduced.
This will update mouse position with given coordinate (`<x>`, `<y>`),
and additionally, send single-click or double-click event if `<button>`
is given.
Closing the video window sends CLOSE_WIN, which is normally mapped to
the "quit" command. The client API normally disables all key bindings,
and closing the window does nothing. It's simply left to the application
to handle this. This is fine - an embedded window can not be destroyed
by user interaction.
But sometimes, the window might be destroyed anyway, for example because
the containing window is destroyed. If this happens, CLOSE_WIN should
better not be ignored. We can't expect client API users to handle this
specially (by providing their own input.conf), so provide some fallback
for this pseudo key binding. The "quit" command might be too intrusive
(not every client necessarily handles "unexpected" MPV_EVENT_SHUTDOWN),
but I think it's still reasonable.
Using the IPC with a program, it's not often obvious that a newline must
be sent to terminate a command. Print a warning if the connection is
closed while there is still uninterpreted data in the buffer.
Print the OS reported error if reading/writing the socket fails. Print
an erro if JSON parsing fails.
I considered silencing write errors if the write end is closed (EPIPE),
because a client might send a bunch of commands, and then close the
socket without wanting to read the reply. But then, mpv disconnects
without reading further commands that might still be buffered, so it's
probably a good idea to always print the error.
Before this commit, this was defined to trigger undefined behavior. This
was nice because it required less code; but on the other hand, Lua as
well as IPC support had to check these things manually. Do it directly
in the API to avoid code duplication, and to make the API more robust.
(The total code size still grows, though...)
Since all of the failure cases were originally meant to ruin things
forever, there is no way to return error codes. So just print the
errors.
If the user has LEFT/RIGHT/etc. bound in his input.conf, then these were
overriding the menu keys in dvdnav mode.
This hack works because the dvdnav crap happens to be the only user of
MP_INPUT_ON_TOP. If it finds a default key binding in the dvdnav menu
section, it will use that, instead of continuing search and possibly
finding the user key bindings meant for normal playback.
...because everything is terrible.
strerror() is not documented as having to be thread-safe by POSIX and
C11. (Which is pretty much bullshit, because both mandate threads and
some form of thread-local storage - so there's no excuse why
implementation couldn't implement this in a thread-safe way. Especially
with C11 this is ridiculous, because there is no way to use threads and
convert error numbers to strings at the same time!)
Since we heavily use threads now, we should avoid unsafe functions like
strerror().
strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and
gives the function different semantics than the POSIX one. It's a bit of
work to convince this piece of shit to expose the POSIX standard
function, and not the messed up GNU one.
strerror_l() is also in POSIX, but only since the 2008 standard, and
thus is not widespread.
The solution is using avlibc (libavutil, by its official name), which
handles the unportable details for us, mostly. We avoid some pain.
Simpler, and leaves the decision to repeat or not fully to the script
(instead of requiring the user to care about it when remapping a script
binding).
Otherwise, mouse button bindings added by mp.add_key_binding() would be
ignored.
It's possible that this "breaks" some older scripts using undocumented
Lua script functions, but it should be safe otherwise.
Fixes#1283.
The fact that it's a generic command prefix that is parsed even when
using the client API is a bit unclean (because this flag makes sense
for actual key-bindings only), but it's less code this way.
This command was actually requested on IRC ages ago, but I forgot about
it.
The main purpose is that the decoding state can be reset without issuing
a seek, in particular in situations where you can't seek.
This restarts decoding from the middle of the packet stream; since it
discards the packet buffer intentionally, and the decoder will typically
not output "incomplete" frames until it has recovered, it can skip a
large amount of data.
It doesn't clear the byte stream cache - I'm not sure if it should.
Especially with other components (libavcodec, OSX stuff), the thread
list can get quite populated. Setting the thread name helps when
debugging.
Since this is not portable, we check the OS variants in waf configure.
old-configure just gets a special-case for glibc, since doing a full
check here would probably be a waste of effort.
The ipc_thread can exit any time, and will free the mp_ipc_ctx when
doing this, leaving a dangling pointer. This was somewhat handled in the
original commit by setting mpctx->ipc_ctx to NULL when the thread
exited, but that was still a race condition.
Handle it by freeing most things after joining the ipc_thread. This
means some resources will not be freed until player exit, but that
should be ok (it's an exceptional error situation).
Also, actually close the pipe FDs in mp_init_ipc() on another error
path.
A vague idea to get something similar what libquvi did.
Undocumented because it might change a lot, or even be removed. To give
an idea what it does, a Lua script could do the following:
-- type ID priority
mp.commandv("hook_add", "on_load", 0, 0)
mp.register_script_message("hook_run", function(param, param2)
-- param is "0", the user-chosen ID from the hook_add command
-- param2 is the magic value that has to be passed to finish
-- the hook
mp.resume_all()
-- do something, maybe set options that are reset on end:
mp.set_property("file-local-options/name", "value")
-- or change the URL that's being opened:
local url = mp.get_property("stream-open-filename")
mp.set_property("stream-open-filename", url .. ".png")
-- let the player (or the next script) continue
mp.commandv("hook_ack", param2)
end)
The event monitor is used to get keyboard events when there is no window, but
since it is a global monitor to the current process, we don't want it in a
library setting.
Commit 64b7811c tried to do the "right thing" with respect to whether
keyboard input should be enabled or not. It turns out that X11 does
something stupid by design. All modern toolkits work around this native
X11 behavior, but embedding breaks these workarounds.
The only way to handle this correctly is the XEmbed protocol. It needs
to be supported by the toolkit, and probably also some mpv support. But
Qt has inconsistent support for it. In Qt 4, a X11 specific embedding
widget was needed. Qt 5.0 doesn't support it at all. Qt 5.1 apparently
supports it via QWindow, but if it really does, I couldn't get it to
work.
So add a hack instead. The new --input-x11-keyboard option controls
whether mpv should enable keyboard input on the X11 window or not. In
the command line player, it's enabled by default, but in libmpv it's
disabled.
This hack has the same problem as all previous embedding had: move the
mouse outside of the window, and you don't get keyboard input anymore.
Likewise, mpv will steal all keyboard input from the parent application
as long as the mouse is inside of the mpv window.
Also see issue #1090.
Originally, all options were copied to ensure that input_ctx remins
thread-safe, even if options are changed asynchronously. But this got
a bit inconsistent. Copy them automatically and reduce some weirdness.
Until now, creating the input_ctx was delayed until the command line
and config files were parsed. Separate creation and loading so that
input_ctx is available from start.
This should make it possible to simplify some things. For example,
some complications with Cocoa were apparently only because input_ctx
was available only "later". (Although I'm not sure if this is still
relevant, or if the Cocoa code should even be organized this way.)
Let us set a different rate and delay.
Needed for the following commit where we set rate and delay reported by weston.
But only if the option native-keyrepeat is set.
Use libwaio to read from pipes (stdin or named pipes) on Windows. This
liberates us from nasty issues, such as pipes (as created by most
programs) not being possible to read in a non-blocking or event-driven
way. Although it would be possible to do that in a somewhat sane way
on Vista+, it's still not easy, and on XP it's especially hard. libwaio
handles these things for us.
Move pipe.c to pipe-unix.c, and remove Windows specific things. Also
adjust the input.c code to make this work cleanly.
Refine the ugly hack from the previous commit, and let the "quit"
command and some others abort playback immediately. For
playlist_next/playlist_prev, still use the old hack, because we can't
know if they would stop playback or not.
This mechanism originates from MPlayer's way of dealing with blocking
network, but it's still useful. On opening and closing, mpv waits for
network synchronously, and also some obscure commands and use-cases can
lead to such blocking. In these situations, the stream is asynchronously
forced to stop by "interrupting" it.
The old design interrupting I/O was a bit broken: polling with a
callback, instead of actively interrupting it. Change the direction of
this. There is no callback anymore, and the player calls
mp_cancel_trigger() to force the stream to return.
libavformat (via stream_lavf.c) has the old broken design, and fixing it
would require fixing libavformat, which won't happen so quickly. So we
have to keep that part. But everything above the stream layer is
prepared for a better design, and more sophisticated methods than
mp_cancel_test() could be easily introduced.
There's still one problem: commands are still run in the central
playback loop, which we assume can block on I/O in the worst case.
That's not a problem yet, because we simply mark some commands as being
able to stop playback of the current file ("quit" etc.), so input.c
could abort playback as soon as such a command is queued. But there are
also commands abort playback only conditionally, and the logic for that
is in the playback core and thus "unreachable". For example,
"playlist_next" aborts playback only if there's a next file. We don't
want it to always abort playback.
As a quite ugly hack, abort playback only if at least 2 abort commands
are queued - this pretty much happens only if the core is frozen and
doesn't react to input.
This means they get special handling for asynchronously aborting
playback, even if the player is "stuck".
Also document "stop". It seems somewhat useful for client API users
(although that will be implemented properly only in the following
commits.)
Not sure why this was originally added as autorepeated. It makes no
sense, because switching between choices should never autorepeat. (For
the normal "add"/"cycle" commands, autorepeat is usually enabled, but
command.c tries to disable it specifically for choice properties.)
Mismatching units in timeout calculation.
Also, as a near-cosmetic change, explicitly wake up the core on the
right time. Currently this does nothing, because the core is woken up
anyway - but it will matter with the next commit.
Do terminal input with a thread, instead of using the central select()
loop. This also changes some details how SIGTERM is handled.
Part of my crusade against mp_input_add_fd().
To handle legacy commands, string replacement is used; the modified
string is returned by parse_cmd_str(), but it also frees all temporary
memory, which includes the replaced string.
Closes#1075.
Continues commit 348dfd93. Replace other places where input was manually
fetched with common code.
demux_was_interrupted() was a weird function; I'm not entirely sure
about its original purpose, but now we can just replace it with simpler
code as well. One difference is that we always look at the command
queue, rather than just when cache initialization failed. Also, instead
of discarding all but quit/playlist commands (aka abort command), run
all commands. This could possibly lead to unwanted side-effects, like
just ignoring commands that have no effect (consider pressing 'f' for
fullscreen right on start: since the window is not created yet, it would
get discarded). But playlist navigation still works as intended, and
some if not all these problems already existed before that in some
forms, so it should be ok.
bstr.c doesn't really deserve its own directory, and compat had just
a few files, most of which may as well be in osdep. There isn't really
any justification for these extra directories, so get rid of them.
The compat/libav.h was empty - just delete it. We changed our approach
to API compatibility, and will likely not need it anymore.
"Shift+X" didn't actually map any key, as opposed to "Shift+x". This is
because shift usually changes the case of a character, so a plain
printable character like "X" simply can never be combined with shift.
But this is not very intuitive. Always remove the shift code from
printable characters. Also, for ASCII, actually apply the case mapping
to uppercase characters if combined with shift. Doing this for unicode
in general would be nice, but that would require lookup tables. In
general, we don't know anyway what character a key produces when
combined with shift - it could be anything, and depends on the keyboard
layout.
Abandon the "old" infrastructure for --input-file (mp_input_add_fd(),
select() loop, non-blocking reads). Replace it with something that
starts a reader thread, using blocking input.
This is for the sake of Windows. Windows is a truly insane operating
system, and there's not even a way to read a pipe in a non-blocking
way, or to wait for new input in an interruptible way (like with
poll()). And unfortunately, some want to use pipe to send input to
mpv. There are probably (slightly) better IPC mechanisms available
on Windows, but for the sake of platform uniformity, make this work
again for now.
On Vista+, CancelIoEx() could probably be used. But there's no way on
XP. Also, that function doesn't work on wine, making development
harder. We could forcibly terminate the thread, which might work, but
is unsafe. So what we do is starting a thread, and if we don't want
the pipe input anymore, we just abandon the thread. The thread might
remain blocked forever, but if we exit the process, the kernel will
forcibly kill it. On Unix, just use poll() to handle this.
Unfortunately the code is pretty crappy, but it's ok, because it's late
and I wanted to stop working on this an hour ago.
Tested on wine; might not work on a real Windows.
For --input-test, print messages on terminal by default.
Raise message level for enabling input sections, because the OSC makes
this very extremely annoying.
When a new event was added, merely a flag was set, instead of actually
waking up the core (if needed). This was ok in ancient times when all
event sources were part of the select() loop. But now there are several
cases where other threads can add input, and then you actually need to
wakeup the core in order to make it read the events at all.
Apparently this switch means all mouse input should be strictly
rejected. Some VO backends (such as X11) explicitly disable all mouse
events if this option is set, but others don't. So check them in
input.c, which increases consistency.
Follow up on commit 760548da. Mouse handling is a bit confusing, because
there are at least 3 coordinate systems associated with it, and it
should be cleaned up. But that is hard, so just apply a hack which gets
the currently-annoying issue (VO backends needing access to the VO) out
of the way.
"loadfile filename append-play" will now always append the file to the
playlist, and if nothing is playing yet, start playback. I don't want to
change the semantics of "append" mode, so a new mode is needed.
Probably fixes issue #950.
Key bindings are decided on the "down" event, so if the prefix is not
unique, the first/shortest will be used (e.g. when both "a" and "a-b"
are mapped, "a" will always be chosen).
This also breaks combining multiple mouse buttons. But it seems users
expect it to work, and it's indeed a bit strange that it shouldn't work,
as mouse bindings are emitted on the key "up" event, not "down" (if the
shorter binding didn't emit a command yet, why shouldn't it be
combinable).
Deal with this by clearing the key history when a command is actually
emitted, instead of when a command is decided. This means if both
MOUSE_BTN0 and MOUSE_BTN0-MOUSE_BTN1 are mapped, the sequence of holding
down BTN0 and then BTN1 will redecide the current command. On the other
hand, if BTN0 is released before BTN1 is pressed, the command is
emitted, and the key history is deleted. So the BTN1 press will not
trigger BTN0-BTN1.
For normal keys, nothing should change, because commands are emitted on
the "down" event already, so the key history is always cleared.
Might fix#902.
CC: @mpv-player/stable (if this fix is successful)
Something like "char *s = ...; isdigit(s[0]);" triggers undefined
behavior, because char can be signed, and thus s[0] can be a negative
value. The is*() functions require unsigned char _or_ EOF. EOF is a
special value outside of unsigned char range, thus the argument to the
is*() functions can't be a char.
This undefined behavior can actually trigger crashes if the
implementation of these functions e.g. uses lookup tables, which are
then indexed with out-of-range values.
Replace all <ctype.h> uses with our own custom mp_is*() functions added
with misc/ctype.h. As a bonus, these functions are locale-independent.
(Although currently, we _require_ C locale for other reasons.)
Similar to previous commits.
This also renames --doubleclick-time to --input-doubleclick-time, and
--key-fifo-size to --input-key-fifo-size. We could keep the old names,
but these options are very obscure, and renaming them seems better for
consistency.
Convert all these commands to properties. (Except tv_last_channel, not
sure what to do with this.) Also, internally, don't access stream
details directly, but dispatch commands with stream ctrls.
Many of the new properties are a bit strange, because they're write-
only. Also remove some OSD output these commands produced, because I
couldn't be bothered to port these.
In general, this makes everything much cleaner, and will also make it
easier to e.g. move the demuxer to its own thread.
Don't bother updating input.conf, but changes.rst documents how old
commands map to the new ones.
Mostly untested, due to lack of hardware.
Binding multiple commands at once where always considered not
repeatable, because the MP_CMD_COMMAND_LIST wasn't considered
repeatable.
Fixes#807 (probably).
The quit command has an optional argument that is used as exit code.
Extend that to the quit_watch_later command. Actually, unify the
implementations of the two commands.
Requested in #798.
These are now equivalent to combining commands with the "cycle pause" or
"set pause" commands, and thus are not needed anymore. They were also
obscure and undocumented.
This can happen when the input stream is somehow blocking on network,
and the user still send input in one way or another, and one of the
commands is a compound command ("cmd a ; cmd b").
This essentially reverts commit cca13efb. The code in the if was
supposed to be run only if the mouse button was down, because in this
case the mouse area is never considered to be left. Since it was run
for every mouse button, mouse_leave wasn't sent.
Fixes#745.
pthread_equal() returns 0 if the threads are not the same, and somehow
I got that wrong. The worst is that I actually explicitly checked the
manpage when I wrote this code.
The interrupt callback will can be called from another thread if the
cache is enabled, and the stream disconnects. Then stream_reconnect()
will call this function from within the cache thread.
mp_input_check_interrupt() is not thread-safe due to read_events() not
being thread-safe. It will call input callbacks added with
mp_input_add_fd() - these callbacks lead to code not protected by locks,
such as reading X11 events.
Solve this by adding a stupid hack, which checks whether the calling
thread is the main playback thread (i.e. calling the input callbacks
will be safe). We can remove this hack later, but it requires at least
moving the VO to its own thread first.
This used global variables for the asynchronous interrupt callback.
Pick the simple and dumb solution and stuff the callback into
mpv_global. Do this because interrupt checking should also work in the
connect phase, and currently stream creation equates connecting.
Ideally, this would be passed to the stream on creation instead, or
connecting would be separated from creation. But since I don't know yet
which is better, and since moving stream/demuxer into their own thread
is something that will happen later, go with the mpv_global solution.
This is for the sake of multi-key commands again. This could break:
SPACE ignore
SPACE-SPACE command
while this worked:
SPACE-SPACE command
SPACE ignore
The reason being that if the shorter command was first in the list,
it would obviously match, and searching was stopped.
This is for the sake of multi-key combinations (see github issue #718).
Now a multi-key sequence isn't matched if any of the previous keys were
actually mapped.
We only need to track key up/down for a single key. There may be some
minor loss of robustness, but this can (probably) happen only if a VO or
user sends strange or complicated sequences of events. In the normal
case, what we do is more than enough. Most simplification comes from the
fact that mpv is not a game console, and users normally execute only one
action at once.
The window close button is usually mapped to the CLOSE_WIN pseudo-key.
Until now, --input-test treated this pseudo-key like any other key (like
the rest of the input handling code), so you couldn't close the window
in this mode. The manpage had silly instructions and warnings how to
deal with this.
Just always quit when CLOSE_WIN is received, and improve the
instructions.
The input code always supported combinations of multiple keys (even in
MPlayer, although there the code was active really only for mouse
buttons). This was arcance and also made the code more complicated. I
only know of a single person who ever made use of this feature.
Remove this feature, and repurpose some of the support code (e.g.
parsing, display of key combinations, etc.) to handle such multi-
combinations as sequences, instead of keys to be pressed at the same
time. This is much simpler and implements the feature requested in
github issue #718.
This commit will probably cause a bunch of regressions, since the input
handling code has some weird corner cases. I couldn't find any problems
when testing, though.
The recent change of waking up the playback thread using a wakeup pipe
doesn't work on windows, because windows is horrible. So use a condition
variable instead to wake up the thread. To make things worse, jackaudio
is also horrible and "disallows" the use of mutexes, so all we can do is
implementing a half-solution that is not race condition free.
It would probably better to give up on this lock-free crap in the pull-
API audio path.
Mostly untested.
Same change as in e2184fcb, but this time for pull based AOs. This is
slightly controversial, because it will make a fast syscall from e.g.
ao_jack. And according to JackAudio developers, syscalls are evil and
will destroy realtime operation. But I don't think this is an issue at
all.
Still avoid locking a mutex. I'm not sure what jackaudio does in the
worst case - but if they set the jackaudio thread (and only this thread)
to realtime, we might run into deadlock situations due to priority
inversion and such. I'm not quite sure whether this can happen, but I'll
readily follow the cargo cult if it makes hack happy.
I hate tabs.
This replaces all tabs in all source files with spaces. The only
exception is old-makefile. The replacement was made by running the
GNU coreutils "expand" command on every file. Since the replacement was
automatic, it's possible that some formatting was destroyed (but perhaps
only if it was assuming that the end of a tab does not correspond to
aligning the end to multiples of 8 spaces).
I have some doubts that short reads are even allowed/
possible for /dev/js*, does someone know for sure?

Change script_message to broadcast the message to all clients. Add a new
script_message_to command, which does what the old script_message
command did.
This is intended as simplification, although it might lead to chaos too.
This might be helpful if we ever want cascading config files. Also, we
will probably need it if we change the default input.conf bindings, and
want to provide compatibility input.conf files.
This was broken by commit bb6b543812. Note that the original pull
request was fine, but it was broken by my own stupidity when I was
"improving" it.
The problem is that the new loadfile argument was not considered
optional anymore after my changes. The original pull request did handle
this by setting .defval to a dummy value, but I removed that part.
Fix it again by introducing a flag that designates that the parameter is
optional. (I didn't want to add it to m_option.h, because technically,
all options are optional, and it's not possible to have non-optional
options.)
Until now, strings were the only allowed dynamically allocated argument
type in input commands. Extend it so that it works for any type. (The
string expansion in command.c is of course still string specific.)
MP_CMD_COMMAND_LIST commands (used to implement key bindings with
multiple commands) were not checked for abort commands. Implement it.
Remove the remarks about multi-commands being special from the manpage.
Seek coalescing is handled differently now, and the issue with abort
commands is fixed with this commit.
This is a regression introduced from moving Lua scripts (including the
OSC) to their own threads. Now OSC and dvdnav can add their bindings at
the same time without coordination, which seems to result in the OSC
winning most time, and thus overriding the dvdnav menu bindings.
Fix this by adding a flag that makes dvdnav menu bindings take priority
over all other bindings.
I don't like this function at all, but it's basically a trick to get the
input's mp_log instance in a case the mp_input_parse_cmd_strv() is
almost certainly not going to output anything. But still make it
somewhat more consistent with mp_input_parse_cmd_strv() - why force the
caller to always use MP_ON_OSD_AUTO?
Both X11 and Wayland support the same format for drag & drop operations
(text/uri-list), and the code for that was copied from x11_common.c to
wayland_common.c. Factor it out.
This code is shared between input.conf parser and option parser. Until
now, the performance didn't really matter. But I want to use this code
for JSON parsing too, and since JSON will have to be parsed a lot, it
should probably try to avoid realloc'ing too much.
This commit moves parsing of C-style escaped strings into a common
function, and allows using it in a way realloc can be completely
avoided, if the already allocated buffer is large enough.
stream_read_complete() fails if the file is larger than the requested
maximum size. But input.c didn't check for this case, and no indication
that something went wrong was printed.
There's a single mp_msg() in path.c, but all path lookup functions seem
to depend on it, so we get a rat-tail of stuff we have to change. This
is probably a good thing though, because we can have the path lookup
functions also access options, so we could allow overriding the default
config path, or ignore the MPV_HOME environment variable, and such
things.
Also take the chance to consistently add talloc_ctx parameters to the
path lookup functions.
Also, this change causes a big mess on configfiles.c. It's the same
issue: everything suddenly needs a (different) context argument. Make it
less wild by providing a mp_load_auto_profiles() function, which
isolates most of it to configfiles.c.
Always pass around mp_log contexts in the option parser code. This of
course affects all users of this API as well.
In stream.c, pass a mp_null_log, because we can't do it properly yet.
This will be fixed later.
Until now, there were two functions to add input sources (stuff like
stdin input, slave mode, lirc, joystick). Unify them to a single
function (mp_input_add_fd()), and make sure the associated callbacks
always have a context parameter.
Change the lirc and joystick code such that they take store their state
in a context struct (probably worthless), and use the new mp_msg
replacements (the point of this refactoring).
Additionally, get rid of the ugly USE_FD0_CMD_SELECT etc. ifdeffery in
the terminal handling code.
So you can pass a command as list of strings (each item is an argument),
instead of having to worry about escaping and such.
These functions also take an argument for the default command flags. In
particular, this allows setting saner defaults for commands sent by
program code.
Expose this to Lua as mp.send_commandv command (suggestions for a better
name welcome). The Lua version doesn't allow setting the default command
flags, but it can still use command prefixes. The default flags are
different from input.conf, and disable OSD and property expansion.
Remove these because I'm too lazy to convert them to proper
STREAM_CTRLs. Considering that probably nobody uses radio://, caring
about this is a complete waste of time. I will add these commands back
if someone asks for them, but I don't expect this to happen.
Since m_option.h and options.h are extremely often included, a lot of
files have to be changed.
Moving path.c/h to options/ is a bit questionable, but since this is
mainly about access to config files (which are also handled in
options/), it's probably ok.
Tis drops the silly lib prefixes, and attempts to organize the tree in
a more logical way. Make the top-level directory less cluttered as
well.
Renames the following directories:
libaf -> audio/filter
libao2 -> audio/out
libvo -> video/out
libmpdemux -> demux
Split libmpcodecs:
vf* -> video/filter
vd*, dec_video.* -> video/decode
mp_image*, img_format*, ... -> video/
ad*, dec_audio.* -> audio/decode
libaf/format.* is moved to audio/ - this is similar to how mp_image.*
is located in video/.
Move most top-level .c/.h files to core. (talloc.c/.h is left on top-
level, because it's external.) Park some of the more annoying files
in compat/. Some of these are relicts from the time mplayer used
ffmpeg internals.
sub/ is not split, because it's too much of a mess (subtitle code is
mixed with OSD display and rendering).
Maybe the organization of core is not ideal: it mixes playback core
(like mplayer.c) and utility helpers (like bstr.c/h). Should the need
arise, the playback core will be moved somewhere else, while core
contains all helper and common code.
Fix off-by-one error in range check.

Conflicts:
input/input.c
This code is already quite different from mplayer-svn, but still the
same bug.
"screenshot" now maps to "screenshot subtitles" by default, instead of
"screenshot video". Swap the argument order: the more useful argument
should come first. Remove the compatibility aliases for numeric choices
(e.g. "screenshot 1 0" won't work anymore).
This adds a new screenshot mode "subtitles", which basically takes the
video frame as decoded, and renders subtitles into it.
This may fail for some pixel formats, because libswscale sucks. If this
becomes ever a real problem, the code could be changed to convert the
image to RGBA first (or whatever the image writer wants), and then
render the subtitles into it. This would avoid the additional image
copy needed with vo_xv too. But for now, it seems better to go with the
current method in the common case: vo_opengl creates an image copy
anyway, and drawing bitmaps to yv12 is better, as no color space
conversion is involved in draw_bmp.c's up/downsampling conversion.
In input test mode, key bindings won't be executed, but are shown on the
OSD. The OSD includes various information, such as the name of the key,
the command itself, whether it's builtin, and the config file location
it was defined.
The input test mode can be enabled with "--input=test". No effort is
spent trying to react to key bindings that normally exit the player;
they are treated just like any other binding.
If parsing a command fails, its location is printed. The location is
the path to the input.conf, and the line number of the key binding and
the associated input command.
Always recognize input commands for optional features (like TV commands
etc.). If these features are disabled, the commands are parsed, but
simply do nothing.
This fixes annoying warnings on start with the default/builtin
input.conf, if certain optional features are not compiled.
This changes the name of this project to mpv. Most user-visible mentions
of "MPlayer" and "mplayer" are changed to "mpv". The binary name and the
default config file location are changed as well.
The new default config file location is: ~/.mpv/
Remove etc/mplayer.desktop. Apparently this was for the MPlayer GUI,
which has been removed from mplayer2 ages ago.
We don't have a logo, and the MS Windows resource files sort-of require
one, so leave etc/mplayer.ico/.xpm as-is.
Remove the debian and rpm packaging scripts. These contained outdated
dependencies and likely were more harmful than useful. (Patches which
add working and well-tested packaging are welcome.)
Allow the values "up" and "down" as step argument for the cycle input
command. Previously, this argument was a float, which specified an
arbitrary step value and direction (similar to the add command).
Instead of "1" and "-1", "up" and "down" is to be used.
Float values are still accepted. That capability might be removed in the
future, as there's probably hardly any actual use for arbitrary step
values.
This disables warning messages when the legacy input command bridge is
used. For now, user input.confs should just keep working as if nothing
has changed. The deprecation warnings will be enabled again at a later
point, and the legacy bridge will be eventually removed.
The "no-osd" prefix was introduced earlier to disable OSD selectively
based on the key binding. Extend this, and allow the user to force
display of an OSD bar ("osd-bar"), OSD message ("osd-msg") or both
("osd-msg-bar"). This changes mainly how property setting functions
behave.
The default behavior is still the same.
Allow using the choice type (as it used for command line) for arguments
of input commands. Change the magic integer arguments of some commands
(like seek) to use choices instead. The old numeric values are still
allowed (but only those which made sense before, not arbitrary
integers).
In order to do this, remove the input.c specific types (like
MP_CMD_ARG_INT) completely and specify commands using the m_option
types.
Also, add the special choice "-" to some arguments. It's supposed to
signify the default value, so arguments can be easily skipped. Maybe the
choice option should recognize this and not change the previous value,
but we'll leave this for later.
For now, leave compatibility integer values for all new choice
arguments, e.g. "0" maps to 0. We could let the choice option type do
this automatically, but we don't, because we want user input values and
internal mplayer values decoupled in general. The compatibility options
will be removed one day, too.
Also, remove optional args for strings - would require either annoying
additional code, or copying strings twice. It's not used, so remove it.
If a command is not found, warn about it at loading time (just like
other command parsing errors are printed at loading time).
Add an explicit "ignore" command. input.conf instructs users to use this
command to cancel out existing mapping. This clashed with the
warning added in this commit. Make "ignore" a real command and remove
the specialcasing for it from get_cmd_from_keys(). Now "ignore" is
ignored because it's not handled in command.c.
Previously, both the command parser and property expansion
(m_properties_expand_string) handled escapes with '\'. Move all escape
handling into the command parser, and remove it from the property code.
This removes the need to escape strings twice for commands that use
property expansion.
The command parser is practically rewritten: it uses m_option for the
actual parsing, and reduces hackish C-string handling.
When input.conf is loaded, verify each command and print a warning if
it's invalid or uses legacy commands. This is done for both the user's
and the embedded config files.
The diff is a bit noisy, because mp_input_parse_cmd() is changed to take
a bstr as argument instead of a char*.
Now it depends on the command whether a property wraps around, or stops
at min/max valid property value.
For practically all properties, it's quite unambiguous what the "switch"
command should have done, and there's technically no need to replace it
with these new commands. More over, most properties that cycle are
boolean anyway. But it seems more orthogonal to make the difference
explicit, rather than hardcoding it. Having different commands also
makes it more explicit to the user what these commands do, both just due
to the naming, and what wrapping policy is used. The code is simpler
too.
Move the code for "switch_ratio" to the M_PROPERTY_SET case of the
"aspect" property. The rules are exactly the same, e.g. setting a ratio
smaller than 0.1 sets the pixel aspect ratio to 1:1. For now, we define
that writing "0" sets the PAR to 1:1, and disallow -1 (possibly reserve
it to reset to default aspect ratio).
Replace --hardframedrop with --framedrop=hard. Rename the framedrop
property from "framedropping" to "framedrop" for the sake of making
command line options have the same name as their corresponding
property. Change the property to accept choice values instead of
numeric values.
Remove unused/forgotten auto_quality variable.
osd_show_[property_]text => show_text
osd_show_progression => show_progress
show_text, osd_show_property_text and osd_show_text both map to the
code for the previous osd_show_property_text. The only special thing
about osd_show_text is that you don't need to escape "$". Also,
unfortunately osd_show_property_text requires escaping things twice,
one time for the command parser, and the other time for the property
formatting code, while osd_show_text needed only one level of escaping.
Use "-" instead of "_" in property names. The intent is that property
names and options names should be the same (if they refer to the same
thing), and options use "-" as word separator.
Rename some other properties too, e.g. "switch_audio" -> "audio".
Add a way to translate the old property names to the new ones, similar
to the input command legacy bridge.
Update input.conf. Use the new property names, and don't use legacy
commands.
Most input commands had their own policy whether to display an OSD
message for user feedback or not. Some commands had two variants, one
that showed an OSD message and one that didn't (e.g. step_property_osd
and step_property).
Change it such that all commands show a message on the OSD. Add a
"no-osd" modifier that disables OSD for that command. Rename the
"step_property" and "step_property_osd" command to "switch", and rename
"set_property" and "set_property_osd" to "set".
Note that commands which haven't used OSD before still don't use OSD.
That will possibly be fixed later. (E.g. "screenshot" could display an
OSD message instead of just printing a message on the terminal.)
The chapter and edition properties still produce OSD messages even with
"no-osd", because they don't map so well to the property_osd_display[]
mechanism.
There are many input commands which are redundant to properties. They
were parsed like normal commands, but set_property_command() in
command.c handled them automatically using the property mechanism. This
still required having the command specifications around, and the code in
command.c was quite messy.
Replace this with a text based replacement mechanism. Some corner cases
are not handled: commands of form "seek_chapter 3 1" are supposed to set
the "chapter" property to 3. This use is probably rare, and doesn't show
up in the default input.conf.
The reason compatibility is kept is because breaking input.conf is quite
annoying, so a minimal effort is made to avoid this. Currently we print
an annoying warning every time a legacy command is used, though.
Also add a compatibility entry for "pt_step", which was removed some
time ago. Variations in whitespace are not handled, but it's good enough
to deal with old input.conf entries.
These have been replaced by properties. Also remove some other slave-
mode specific get commands that can be replaced by property uses.
The get_metadata() function didn't actually contain anything useful,
and just replicated code from other parts of mplayer.
